 KIM MEMORIAL VOLUME.
The following three papers are author versions of
papers which appeared in the
Kim memorial volume,
Acta Applicandae Mathematicae 126 (2013),
for which I was the guest editor.
There is a
Mathnet link
and a
Springer link
for the volume.
For each of the three papers, the final publication is available at
